S-97349A417 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and ensuring long-term reliability in plastic assemblies.
• Efficient thread forming design (DST type) creates strong, secure threads in plastic materials without pre-tapping, reducing installation time and labor costs.
• Optimized Phillips pan head with No. 1 drive size provides excellent torque transfer and a low-profile finish, minimizing snagging and improving aesthetics.
• Precise dimensional accuracy with fully threaded No. 4-24 right-hand threads and 1/2" length, ensuring consistent performance and easy alignment in plastic components.
• Enhanced material compatibility using a No. 44 drill bit (0.086" diameter) for clean hole preparation, reducing stress cracking in plastic substrates.
• Full regulatory compliance with RoHS 3 and REACH standards, guaranteeing safe, environmentally responsible use in industrial and consumer applications.
• Durable blunt tip and rounded head profile prevent damage to plastic surfaces during installation, maintaining structural integrity and product appearance.

Professional Applications & Engineering Value

These No. 4-24 x 1/2" tapping screws are engineered to address common challenges in plastic assembly, such as material cracking and thread stripping. The 18-8 stainless steel offers excellent strength and corrosion resistance, while the thread forming (DST) technology displaces plastic material to create robust, vibration-resistant threads without chips or debris. This design is ideal for plastic components in electronics, automotive trim, and consumer goods, where reliable fastening and aesthetic appeal are critical. The Phillips pan head ensures efficient drive engagement, reducing cam-out risks and speeding up production lines. By integrating these tapping screws, manufacturers achieve faster assembly cycles, reduced part failure, and compliance with industry regulations like RoHS and REACH.
